Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1270-1291, May 2026.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

Achieving Functionality Targets for Seismically Isolated Steel Buildings Using Gaussian Process Modeling

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
As seismic design paradigms shift toward functional recovery, there is a need for efficient methods to achieve desired decision variables (DVs), such as probability of replacement, repair cost, and downtime of the building, for seismically isolated buildings.

Joint Angular Excursions and Angular Range Utilization During Stance‐Phase Locomotion in Terrestrial Mammals: A Comparative Morphofunctional Data Set

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 4, Page 361-376, May 2026.
This study quantifies stance‐phase joint angular excursions and angular utilization (AUI%) during walking in 182 terrestrial mammal species. Across mammals, total limb excursion during stance (TAE) decreases with increasing body mass, whereas AUI% remains broadly conserved, indicating similar proportional use of summed joint excursions to generate net ...

High‐Velocity Ballistic Impact Performance of FFF Printed PEEK With Different Infill Patterns

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
This study examines 3D printed PEEK under Izod, quasi‐static, and high‐velocity impact. Hexagonal infill shows the highest Izod impact strength and superior quasi‐static energy absorption. However, under ballistic impact, all patterns behave similarly, indicating performance depends on infill at low velocity, but on intrinsic material properties at ...

Pendulum: from the Simple to Complex and Backward

open access: yesФилологический класс, 2012
The article focuses on the the dichotomies of simplicity and complexity in Russian literature of the 20th century. The author proposes hypothesis that simplistic and complex tendencies in cultural history correlate with the two opposite scenarios of ...
